Bra Buying Guide

For many, buying a bra can be a harrowing experience, but here at Zodee we are trying to make this as simple and even as enjoyable as possible. We hope to guide you in finding the bra that's perfect for you and explain some of the terminology used by bra manufacturers that feels like it's just there to confuse you!

Fitting Guide

The first step in buying any bra is getting the size right. Did you know that as many as 80% of people are wearing the wrong sized bra? Could that be you? Surely not! Then what's the harm in measuring yourself anyway - you might get a surprise! Many people are convinced of their size and have been wearing the same (wrong) size for 20 years or more! Your body does change over time, and so should your bra wardrobe! We encourage you to keep an open mind when measuring for bras.

Bra sizes are calculated based on two measurements; your underbust and bust. It is the combination of these sizes that determines the correct size for your you. The cups are sized relative to the band, so if you were to try a smaller band size but keep the same cup size, the cups would be too small. If you need to drop a band size, you will need to increase the sup size by one to compensate. For example, if a 12C bra is the right cup size but is too big in the back, then you should try a 10D. Not obeying this rule is the most common issue when fitting for a bra and should not be ignored.

Step 1 : Measure Your Underbust

Measuring Your BandWhilst wearing your most comfortable bra, but no clothing, with a standard measuring tape (not a rigid one) place the tape on your rib cage directly under the bust as pictured.

► The tape should be straight (not up or down at the back) and be reasonably taut, but neither loose or tight.

► Using a mirror will aid you in getting the tape as straight as possible.

This is your back measurement or band size. Take a note of this measurement in centimetres, rounding to the nearest centimetre.

Step 2 : Measure Your Bust

Measuring Your Bust SizeAgain with your bra on, place the bra on the largest, fullest part of your breast, as shown and record the size in centremetres.

► The tape should not be too tight as to change the shape of your breast.

► Ensure that the tape is straight across the back, again using a mirror to aid.

Record this measurement in centimetre, again, rounding to the nearest centimetre.

Step 3 : Determine Your Ideal Bra Size

Once you have these 2 measurements, use the this sizing chart to determine your ideal size.

  1. 1. Follow across the top row until you find the correct measurements for you under bust, with the Band Size Directly underneath
  2. 2. The follow the table down until you reach the appropriate Over Bust measurement and read the cup size from the left

For example, if your Under Bust measurement is 75cm and your Over Bust measurement is 92 cm, then according to the chart you are a 12C.

Choosing The Right Bra

Choosing a bra is depends upon many factors, quite apart from choosing the right size. Some of these are are simply personal preference, such as the amount of cup coverage you need, some depend on your size as you may require more support not available in all styles. It also depends on the garments that you choose to wear on top of your bra.

Cup Shape

Contour - A cup that has a defined shape from light padding.

Unmoulded - A cup that has no defined shape with flimsy material.

Cup Design

Full Cup - Cups that cover the entire breast.

Demi Cup - Also known as a half cup bra, cups cover half of the breast.

Balconette - Low cut style with wide set straps. A shallower U shaped underwire is used and is designed to be more revealing and to create cleavage.

Soft Cup - Gets support from the under bust band without the use of underwire.

Specialist Bras

Sports - Coming in different levels of support, a sports bra is designed to be close fitting to reduce movement whilst exercising.

Maternity - A maternity bra is designed to be adjusted over the course of pregnancy. Most styles have additional hooks & eyes for your changing rib cage. Available without underwire and with flexi wires so as not to block milk ducts under the arm.

Nursing - Designed to provide quicker, easier access to the nipple for breastfeeding babies. Clips on the straps allow the cup to drop down and can be supported with an A-Frame. Usually lined with cotton and with minimal seams on the cup so irritation doesn't occur.

Mastectomy - Designed for women who have had one or both breasts surgically removed. The cups are double lined, usually with cotton with an opening for a prosthesis to sit comfortably

Post Surgery - Suitable for use straight after sugical operations like a mastectomy, breast augmentation or implants. Most are front opening because of the lack of movement due to the surgery and compression.


Plunge - Plunge bras have a low centre front

Front Closure - Front closure bras have clips, hooks & eyes or velcro fastening fronts and are great when a smooth back is needed or for anyone with limited movement

Adhesive - 2 kinds, reusable and disposable. They adhere to the breast and offer very little support

Racerback - Mainly used in sports bras, the straps go over the shoulder staying close to the neck and form a v shape at the centre of the back used to keep straps from falling off the shoulder.

Longline - Bra band sits further down the torso.

Bandeau - A bra that sits straight across the bust to wear with strapless garments

Wire Free - A wire free or soft cup bra uses banding under the bust to support the bust without the use of underwire.
